1.3Description
The TDA4863 IC controls a boost converter in a way that sinusoidal current is taken fromthe single phase line supply and stabilized DC voltage is available at the output. Thisactive harmonic filter limits the harmonic currents resulting from the capacitor pulsedcharge currents during rectification. The power factor which describes the ratio betweenactive and apparent power is almost one. Line voltage fluctuations can be compensatedvery efficiently.

Description
VSENSEVoltage Amplifier Inverting Input
VSENSE is connected via a resistive divider to the boost converter output. With a capacitor connected to VAOUT the internal error amplifier acts as an integrator.VAOUT
Voltage Amplifier Output
VVAOUT is connected internally to the first multiplier input. To prevent overshoot the input voltage is clamped internally at 5V. If VVAOUT is less than 2.2V the gate driver is inhibited. If the current flowing into this pin exceeds an internal threshold the multiplier output voltage is reduced to prevent the MOSFET from overvoltage damage.
Multiplier Input
MULTIN is the second multiplier input and is connected via a resistive divider to the rectifier output voltage.
Current Sense Input
ISENSE is connected to a sense resistor controlling the MOSFET source current. The input is internally clamped at -0.3V to prevent negative input voltage interaction. A leading edge blanking circuitry suppresses voltage spikes when turning the MOSFET on.Zero Current Detector Input
DETIN is connected to an auxiliary winding and monitors the zero crossing of the inductor current.Ground
Gate Driver Output
GTDRV is the output of a totem-pole circuitry for direct driving a
MOSFET. An active shutdown circuitry ensures that GTDRV is set to low if the IC is switched off.
Positive Voltage Supply
If VCC exceeds the turn-on threshold the IC is switched on. When VCC falls below the turn-off threshold the IC is switched off. In switch off mode power consumption is very low. Two capacitors should be connected to VCC. An electrolytic capacitor and 100nF ceramic capacitor which is used to absorb fast supply current spikes. Make sure that the electrolytic capacitor is discharged before the IC is plugged into the application board.

Functional Description

2.1
Functional Description
Introduction
Conventional electronic ballasts and switch mode power supplies are designed with abridge rectifier and a bulk capacitor. Their disadvantage is that the circuit draws powerfrom the line when the instantaneous AC voltage exceeds the capacitors voltage. Thisoccurs near the line voltage peak and causes a high charge current spike with followingcharacteristics: The apparent power is higher than the real power that means low powerfactor condition, the current spikes are non sinusoidal with a high content of harmonicscausing line noise, the rectified voltage depends on load condition and requires a largebulk capacitor, special efforts in noise suppression are necessary.
With the TDA4863 preconverter a sinusoidal current is achieved which varies in directinstantaneous proportional to the input voltage half sine wave and so provides a powerfactor near 1. This is due to the appearance of almost any complex load like a resistiveone at the AC line. The harmonic distortions are reduced and comply with the IEC555standard requirements.
2.2IC Description
The TDA4863 contains a wide bandwidth voltage amplifier used in a feedback loop, anovervoltage regulator, an one quadrant multiplier with a wide linear operating range, acurrent sense comparator, a zero current detector, a PWM and logic circuitry, a totem-pole MOSFET driver, an internal trimmed voltage reference, a restart timer and anundervoltage lockout circuitry.
2.3Voltage Amplifier
With an external capacitor between the pins VSENSE and VAOUT the voltage amplifieracts like an integrator. The integrator monitors the average output voltage over severalline cycles. Typically the integrator´s bandwidth is set below 20Hz in order to suppressthe 100Hz ripple of the rectified line voltage. The voltage amplifier is internallycompensated and has a gain bandwidth of 5MHz (typ.) and a phase margin of 80degrees. The non-inverting input is biased internally to 2.5V. The output is directlyconnected to the multiplier input.
The gate drive is disabled when VSENSE voltage is less than 0.2V or VAOUT voltageis less than 2.2V.
If the MOSFET is placed nearby the controller switching interferences have to be takeninto account. The output of the voltage amplifier is designed in a way to minimize theseinteferences.

Functional Description
2.4Overvoltage Regulator
Because of the integrator´s low bandwidth fast changes of the output voltage can’t beregulated within an adequate time. Fast output changes occur during initial start-up,sudden load removal, or output arcing. While the integrator´s differential input voltageremains zero during this fast changes a peak current is flowing through the externalcapacitor into pin VAOUT. If this current exceeds an internal defined margin theovervoltage regulator circuitry reduces the multiplier output voltage. As a result the ontime of the MOSFET is reduced.
2.5Multiplier
The one quadrant multiplier regulates the gate driver with respect of the DC outputvoltage and the AC half wave rectified input voltage. Both inputs are designed to achievegood linearity over a wide dynamic range to represent an AC line free from distortion.Special efforts have been made to assure universal line applications with respect to a 90to 270V AC range.
The multiplier output is internally clamped to1.3V. So the MOSFET is protected againstcritical operating during start up.
2.6Current Sense Comparator, LEB and RS Flip-Flop
The source current of the MOS transistor is transferred into a sense voltage via theexternal sense resistor. The multiplier output voltage is compared with this sensevoltage. Switch on time of the MOS transistor is determined by the comparision resultTo protect the current comparator input from negative pulses a current source is insertedwhich sends current out of the ISENSE pin every time when VISENSE-signal is fallingbelow ground potential. An internal RC-filter is connected at the ISENSE pin whichsmoothes the switch-on current spike.The remaining switch-on current spike is blankedout via a leading edge blanking circuit with a blanking time of typ. 200ns.
The RS Flip-Flop ensures that only one single switch-on and switch-off pulse appears atthe gate drive output during a given cycle (double pulse suppression).
2.7Zero Current Detector
The zero current detector senses the inductor current via an auxiliary winding andensures that the next on-time of the MOSFET is initiated immediately when the inductorcurrent has reached zero. This reduces the reverse recovery losses of the boostconverter diode to a minimum. The MOSFET is switched off when the voltage drop ofthe shunt resistor exceeds the voltage level of the multiplier output. So the boost currentwaveform has a triangular shape and there are no deadtime gaps between the cycles.This leads to a continuous AC line current limiting the peak current to twice of theaverage current.

TDA4863
Functional Description
To prevent false tripping the zero current detector is designed as a Schmitt-Trigger witha hysteresis of 0.5V. An internal 5V clamp protects the input from overvoltagebreakdown, a 0.6V clamp prevents substrate injection. An external resistor has to beused in series with the auxiliary winding to limit the current through the clamps.
2.8Restart Timer
The restart timer function eliminates the need of an oscillator. The timer starts or restartsthe TDA4863 when the driver output has been off for more than 150µs after the inductorcurrent reaches zero.
2.9Undervoltage Lockout
An undervoltage lockout circuitry switches the IC on when VCC reaches the upperthreshold VCCH and switches the IC off when VCC is falling below the lower threshold VCCL.During start up the supply current is less then 100µA.
An internal voltage clamp has been added to protect the IC from VCC overvoltagecondition. When using this clamp special care must be taken on power dissipation.Start up current is provided by an external start up resistor which is connected from theAC line to the input supply voltage VCC and a storage capacitor which is connected fromVCC to ground. Be aware that this capacitor is discharged before the IC is plugged intothe application board. Otherwise the IC can be destroyed due to the high capacitorvoltage.
Bootstrap power supply is created with the previous mentioned auxiliary winding and adiode (see “Application Circuit” on Page21).
2.10Gate Drive
The TDA4863 totem pole output stage is MOSFET compatible. An internal protectionciruitry is activated when VCC is within the start up phase and ensures that the MOSFETis turned off. The totem pole output has been optimized to minimize cross conductioncurrent during high speed operation.
